306323 ÷ 72 
We want to figure out the number of times 306323 can be divided by 72.

Going ahead to step 1:
The number 72 fits into 3 0 times, leaving a remainder of 3.
The next digit of our result is 0. 
Result so far: 0.0
Subtract 0 from 3 to get 3.
Include the next digit (0) from the dividend after 3, then repeat: 30 / 72

Going ahead to step 2:
When dividing 30 by 72, we get 0 with a remainder of 30.
Record the quotient 0 as the next digit in the result. 
Result so far: 0.0
Deduct 0 from 30 and we're left with 30.
Take the next digit (6) from the dividend and append it to 30, then repeat: 306 / 72

Advancing to step 3:
The number 72 fits into 306 4 times, leaving a remainder of 18.
Use 4 as the next digit of our solution. 
Result so far: 4.0
If we take 288 away from 306, we end up with 18.
Grab the next digit (3) from the dividend, add it to 18, then carry on: 183 / 72

Advancing to step 4:
72 can be fit into 183 2 times, resulting in a remainder of 39.
Write down 2 as next digit of the result. 
Result so far: 42.0
If we take 144 away from 183, we end up with 39.
Include the next digit (2) from the dividend after 39, then repeat: 392 / 72

Let's proceed to step 5:
392 divided by 72 is 5 with a remainder of 32.
The number 5 becomes the next digit in our result. 
Result so far: 425.0
Subtracting 360 from 392 leaves us with 32.
Bring next digit (3) of the dividend behind the 32 and repeat the process: 323 / 72

Step 6:
72 goes into 323 4 times with a remainder of 35.
The number 4 becomes the next digit in our result. 
Result so far: 4254.0
Subtracting 288 from 323 leaves us with 35.
Since there are no more digits in the dividend, we add a zero to the remainder making it 350, and continue the process.

On to step 7:
When dividing 350 by 72, we get 4 with a remainder of 62.
The next digit of our result is 4. 
Result so far: 4254.4
Deduct 288 from 350 and we're left with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Going ahead to step 8:
When dividing 620 by 72, we get 8 with a remainder of 44.
The number 8 becomes the next digit in our result. 
Result so far: 4254.48
The remainder is 44 after subtracting 576 from 620.
Since there are no more digits in the dividend, we add a zero to the remainder making it 440, and continue the process.

Step 9:
The number 72 fits into 440 6 times, leaving a remainder of 8.
Write down 6 as next digit of the result. 
Result so far: 4254.486
Subtract 432 from 440 to get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

On to step 10:
80 divided by 72 is 1 with a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 4254.4861
Subtracting 72 from 80 leaves us with 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

Let's proceed to step 11:
72 can be fit into 80 1 times, resulting in a remainder of 8.
Record the quotient 1 as the next digit in the result. 
Result so far: 4254.48611
If we subtract 72 from 80, we get 8.
Since there are no more digits in the dividend, we add a zero to the remainder making it 80, and continue the process.

The quotient of the division is 4254.48611, and the remainder is 8e-06.
